From: Michal Privoznik <miso.privoznik@xxxxxxxxx>
In this test there is this macro CHECK_LIST_COUNT() which checks
if a list of PCI devices contains expected count. If it doesn't
an error is reported and 'goto cleanup' is invoked. There's no
real reason for that as even since its introduction there is no
cleanup done and all 'cleanup' labels contains nothing but
'return'.
